<p>PROBLEM TO BE SOLVED: To provide an opening/closing mechanism which is small-sized and excels in operational reliability.SOLUTION: A fuel lid opening/closing mechanism 1 includes: a push rod 10 which reciprocates between a push-in position for closing a fuel lid and a protrusion position for opening the fuel lid; a follower 13 which is installed on the push rod to be rotatable relative to the push rod and moves integrally with the push rod in the axial direction; an energization member 14; and a case 16. The case includes a cam part for the rod 25 which rotates the push rod and a cam part for the follower 26 which rotates the follower according to forward and backward motions of the push rod; the cam part for the follower including a plurality of follower engaging parts 36 which keep the push rod in the push-in position by engaging the follower; the follower engaging parts being arranged at intervals of a rotational angle of rotation of the follower caused by one reciprocating motion of the push rod between the push-in position and the protrusion position.</p> |
